El oído ciclópico: un nuevo sentido para la mantis religiosa
Resumen
Las mantis religiosas, previamente consideradas sordas, tienen un sentido auditivo especializado en ultrasonido. Esta capacidad acústica les permite detectar la ecolocalización del murciélago y alterar las trayectorias de vuelo, mejorando la supervivencia.
Área de la Ciencia:
- * La bioacústica es la bioacústica.
- * Biología sensorial de los insectos.
- * Ecología del comportamiento.
Sus antecedentes:
- * Los insectos a menudo poseen sistemas auditivos para la detección de depredadores.
- * Las mantis religiosas fueron tradicionalmente consideradas sordas.
- * La ecolocalización del murciélago representa una amenaza para los insectos voladores.
Objetivo del estudio:
- * Investigar las capacidades auditivas de las mantis religiosas.
- * Para caracterizar el rango de frecuencias y la sensibilidad de la audición de la mantis.
- * Para explorar la importancia funcional de la detección acústica en las mantis.
Principales métodos:
- * Grabaciones electrofisiológicas del sistema auditivo de la mantis.
- * Estimulación con pulsos ultrasónicos a través de varias frecuencias e intensidades.
- * Observación del comportamiento de las respuestas de vuelo a los estímulos acústicos.
Principales resultados:
- * El sistema auditivo de la mantis responde al ultrasonido (2545 kHz) con umbrales de 5560 dB.
- * Las mantis poseen una única oreja, localizada en el interior, a diferencia de otros insectos.
- * Algunas especies de mantis exhiben maniobras de vuelo evasivas cuando se exponen a ultrasonidos.
Conclusiones:
- * Las mantis religiosas poseen un sistema auditivo funcional de ultrasonido.
- * Esta capacidad auditiva probablemente sirve como un mecanismo de defensa contra los murciélagos.
- * La estructura única de la oreja justifica una mayor investigación.

Hair Cells
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
Epiphytes, Parasites, and Carnivores
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...
The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
